Clock Failure
The onboard Rubidium Atomic Frequency Standard ceases operation, halting navigation services.
Mission Milestone
The satellite officially completes its 10-year design mission life.
Satellite Launch
IRNSS-1F launched into geosynchronous orbit aboard the PSLV-C32 rocket.
The Indian Space Research Organisation (ISRO) has confirmed the failure of the primary atomic clock aboard the IRNSS-1F satellite, occurring just days after the spacecraft completed its decade-long design life. While the failure terminates the satellite's navigation utility, the platform remains operational for secondary messaging services in geosynchronous orbit.
